Paulo Bernardo thinks the best is yet to come from Jota in a Celtic jersey.
The flamboyant Portuguese winger rejoined the Parkhead side in January after spells in Saudi Arabia and France didn't go to plan.
Jota has steadily found his feet since returning to Glasgow's east end, regularly chipping in with goals and assists.
This time around at Celtic, he also has a fellow countryman alongside him in the form of Bernardo.

The midfielder was also signed from Benfica, and revealed how the 26-year-old is grafting behind the scenes in order to reach an optimum level: "Jota has already shown a lot of quality during these games," said Bernardo.
"I spoke to him and he feels much better now than he was when he arrived.
"I think he’s really important to the squad. At his age, I think there is more to come from him, and he came here to show that, too.
"He wants to show his quality, and he is doing really well at the moment. He’s working hard at Lennoxton every day. I think the best will come from him.
"He’s a fantastic footballer and I think he improves the levels in our squad and our strength in many ways. It’s really nice to have him here."
Jota has, on average, contributed to a goal every other game since his emotional Celtic return.
As he continually improves his fitness and familiarises more with Brendan Rodgers' system, further improvements are expected as the attacker looks to reach the heights he did during his first spell in Scotland.
